A heat exchanger system including a controller configured to direct a first power signal to a first cooling fan module to operate a first motor at a first rotational speed to provide a first flow rate to satisfy the first demanded heat rejection rate, direct a second power signal to the second cooling fan module to operate the second motor at a second rotational speed to provide a second flow rate to satisfy the second demanded heat rejection rate while maintaining a rotational speed differential between the first rotational speed and the second rotational speed, such that an acoustic property of at least one of the first heat exchanger assembly and the second heat exchanger assembly is below a predetermined acoustic property threshold.
